Method Float64

encoder/encoder.go:154–172

Float64 handles encoding of 64bit float values according to the ValueEncoder configuration.

(field string, val float64)

// Float64 handles encoding of 64bit float values according to the ValueEncoder configuration.
func (m *ValueEncoder) Float64(field string, val float64) string {

	var (
		result string
		sum    = m.GetSummary(TypeNumeric, field)
	)

	switch {
	case m.conf.ZScore:
		result = ZScore(val, sum)
	case m.conf.MinMax:
		result = MinMax(val, sum)
	default:
		spew.Dump(m.conf)
		log.Fatal("invalid config: no normalization strategy")

	return result

// GetSummary returns the summary for the given column type and field name.
// It will create a new one if none is being tracked yet.
